SPECIFICATION forming part of Letters Patent No. 295,293, dated March18, 1884.

Application filed February 21, 1883. (No model.)

To @ZZ zutont t may concern.:

Be it known that I, LoUIs SoHU'rrn, of Phiiadelphia, in the county ofPhiladelphia, in the State of Pennsylvania., United States of America.,have invented certain new and useful Improvements in Jet-Ejectors, ofwhich the following is a specification.

The present invention consists in the peculiar construction and relativearrangement of the severai parts oi' a steani-ejector for the purposeoi' producing an apparatus of the smallest possible size incross-section.

Itelerring to the accompanying drawings, Figure 1 represents a verticalcentral crosssection of my apparatus. Fig. 2 is a side'elevation ot' thesame. on the line of Fig. 1.

In proceeding to construct my apparatus I iirst cast complete in onepiece a body, I, of the forni represented in the drawings, with twoattened sides and a semici'rcular lower end. vWithin this body there isformed a revertible opening or passageVG, which communicates at itsupper end near one side of the body with a tnbular neck or throat, whichis threaded eX- ternally to receive the couplingi'or connecting thesteam-pipe D therewith. At its opposite and inner end the passage GfVterminates in a steam-nozzle, A, the mouth of which is extended in anupward direction. At its lower end the body has formed upon it a tubularcentral neck, which is threaded internally to receive and suspend thesuction-pipe F, through which the water or other fluid to be elevatedmay be drawn into the apparatus. Into the top ofthe body, directly overthe nozzle A, I screw the combining-tube C, the lower end of which isexpanded to encircle the steam-nozzle A, and the upper end of which ismade of iilcreasing diameter toward its delivery end.

It will be observed that the tube C is provided with au external threadand screwed into place in the top of the body I, this constructionpermitting the tube to be readily re- Fig. 3 is a cross-sectionmoved inorder to give access to the interior ofthe apparatus in the event of itsbecoming necessary.

To the upper end of the mixing-tube C-,I connect, by asuitablecoupling-joint, the vertical delivery-pi pe E;

It will be observed that the steam-pipe D and delivery-pipe E stand in avertical position, and that they connect with the top of the body nearopposite sides thereof, so that they serve jointly to sustain the weightof the body and ofthe pendent suctionpipe F. This arrangement admitsofthe Weight being distributed between the two upper pipes, and alsodisposes of the weight in such manner that the devices have little or noliability to vibrate when in action.

Around the steain'pipe D, concentric therewith, I mount a second pipe,H, the lower end of which is attached to a coupling to receive thesteam-pipe.

pipes D and H for the purpose of preventing the condensation of thesteam by the cold fluids in which the apparatus is ordinarily submerged.

I am aware that various ejectors have been constructed with steam anddelivery pipes at the top and a suction-pipe at the bottonnand LOUISSCHUTTE.
